Crazy Canuck

Hey all,

I brought my Revo with me while I was on a vacation up at the cottage and had it jumping a small ramp we had set up on the front lawn. While in mid-air I heard a snap and thought nothing more of it after the landing as the Revo was still working. I put it away for the night and went to use it the next day but it would barely move. It would also shift from forward to reverse on it's own. It has brand new servo's (JR Z590's) and a brand new opti drive unit. The clutch is spinning when I give it some throttle but I'm thinking it's a gear in the transmission that may be stripped or broken. Any ideas or suggestions on what could be wrong and how difficult is it to get into the tranny??

Cheers
